Nene was returned to the position during President Cyril Ramaphosa's cabinet reshuffle on Monday. Nene had been unceremoniously fired by former president Jacob Zuma in December 2015, wiping billions off the stock market.

Moyane said that SARS' leadership previously had a collegial and effective working relationship.

"The return to the portfolio provides yet another opportunity for SARS to strengthen its effective working relationship with Minister Nene and the National Treasury in the effort to successfully collect revenue to support the government’s developmental agenda," Moyane said in a statement.

"SARS appreciates Minister Nene's passion, experience and insightful leadership which will enhance the organisation’s commitment to being an efficient and effective tax authority."

Moyane said that Nene's leadership will further galvanise the SARS workforce and boost morale in a challenging economic environment.
